by St Nikolai Velimirovich
As much as the saints were so compassionate and lenient toward human weakness, so were they terribly unyielding and unbending in regard to the confession of the true dogmas of the Faith.
Thus, St. Nicholas of Myra in Lycia struck Arius with his fist at the First Ecumenical Council [Nicaea, 325 A.D.].
St. Anthony left his desert to come to Alexandria to publicly unmask Arius.
St. Euthymius, being greatly pressured by the Empress Eudocia and the pseudo-Patriarch Theodosius and being unable to debate rationally with them, left the monastery and hid in the desert.
All other distinguished monks followed his example. Euthymius remained in the desert until the pseudo-patriarch was ousted and Orthodoxy strengthened. When, in Jerusalem, the greatest agitation surfaced in the name of the emperor against the Fourth Ecumenical Council [Chalcedon, 451 A.D.] and when the entire population was frightened by the heretics, then St. Theodosius the Great already burdened with old age, as a fearless soldier of Christ, came to Jerusalem, entered the Great Church, ascended the stairs, waved his hands and said to the people,
“If anyone does not respect the Fourth Ecumenical Council as he does the four evangelists, let him be anathema.”
(Until this time, only four Ecumenical Councils had been convened). All of those listeners were frightened by those words and none of the heretics dared to say anything contrary to those words.
